CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a bypass continuation application of International Application No. PCT/KR2022/009620, filed on Jul. 4, 2022, which is based on and claims priority to Korean Patent Application No. 10-2021-0089972, filed on Jul. 8, 2021, in the Korean Intellectual Property Office, the disclosures of which are incorporated by reference herein in their entireties.

BACKGROUND 1. Field

Various embodiments relate to an electronic device including a plurality of touch screen displays and a screen split method.

2. Description of Related Art

Electronic devices are evolving from uniform shapes into structures for expanding a display or improving utilization of a display. An electronic device may have a transformable structure capable of adjusting a size of a display. For example, the electronic device may operate in an in-folding, out-folding, or in/out-folding manner by rotating a first housing and a second housing about each other. In another example, the electronic device may operate in a manner in which the first housing and the second housing slide/or are rolled.

In an electronic device (e.g., a foldable electronic device) in which two housings are folded or unfolded with respect to each other, a first housing and a second housing are rotated through a hinge device, and thus a display structure may be transformed to have various shapes.

The electronic device may variably operate a display area in which information is displayed according to a change in display structure. The electronic device applies a split screen function or a pop-up screen function when performing multitasking of a plurality of applications at the same time. However, to enter a screen split function in the electronic device, a user inconveniently needs to manipulate a touch a plurality of times. Further, a menu structure having a depth (e.g., upper menu and lower menu) is not intuitive to the user, and if the user does not know a configuration location for the screen split function, the user inconveniently needs to check a configuration menu for the split screen function one by one. In addition, the electronic device may cause inconvenience in recognizing information to the user due to overlapping of screen windows during the pop-up screen function.

Therefore, according to a new display structure that is transformed into various forms, a new intuitive interaction method may be required for the user to operate a split screen in relation to a currently running screen.

The communication module 190 may support establishing a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device 101 and the external electronic device (e.g., the electronic device 102, the electronic device 104, or the server 108) and performing communication via the established communication channel. The communication module 190 may include one or more communication processors that are operable independently from the processor 120 (e.g., the application processor (AP)) and supports a direct (e.g., wired) communication or a wireless communication. According to an embodiment, the communication module 190 may include a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 194 (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules may communicate with the external electronic device via the first network 198 (e.g., a short-range communication network, such as Bluetooth™, wireless-fidelity (Wi-Fi) direct, or infrared data association (IrDA)) or the second network 199 (e.g., a long-range communication network, such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., LAN or wide area network (WAN)). These various types of communication modules may be implemented as a single component (e.g., a single chip), or may be implemented as multi components (e.g., multi chips) separate from each other. The wireless communication module 192 may identify and authenticate the electronic device 101 in a communication network, such as the first network 198 or the second network 199, using subscriber information (e.g., international mobile subscriber identity (IMSI)) stored in the subscriber identification module 196.

The wireless communication module 192 may support a 5G network, after a 4G network, and next-generation communication technology, e.g., new radio (NR) access technology. The NR access technology may support enhanced mobile broadband (eMBB), massive machine type communications (mMTC), or ultra-reliable and low-latency communications (URLLC). The wireless communication module 192 may support a high-frequency band (e.g., the mmWave band) to achieve, e.g., a high data transmission rate. The wireless communication module 192 may support various technologies for securing performance on a high-frequency band, such as, e.g., beamforming, massive multiple-input and multiple-output (massive MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna. The wireless communication module 192 may support various requirements specified in the electronic device 101, an external electronic device (e.g., the electronic device 104), or a network system (e.g., the second network 199).

According to an embodiment, the antenna module 197 may include a plurality of antennas (e.g., array antennas). In such a case, at least one antenna appropriate for a communication scheme used in the communication network, such as the first network 198 or the second network 199, may be selected, for example, by the communication module 190 (e.g., the wireless communication module 192) from the plurality of antennas. The signal or the power may then be transmitted or received between the communication module 190 and the external electronic device via the selected at least one antenna. According to an embodiment, another component (e.g., a radio frequency integrated circuit (RFIC)) other than the radiating element may be additionally formed as part of the antenna module 197.

According to various embodiments, the antenna module 197 may form a mmWave antenna module. According to an embodiment, the mmWave antenna module may include a printed circuit board, a RFIC disposed on a first surface (e.g., the bottom surface) of the printed circuit board, or adjacent to the first surface and capable of supporting a designated high-frequency band (e.g., the mmWave band), and a plurality of antennas (e.g., array antennas) disposed on a second surface (e.g., the top or a side surface) of the printed circuit board, or adjacent to the second surface and capable of transmitting or receiving signals of the designated high-frequency band.

At least some of the above-described components may be coupled mutually and communicate signals (e.g., commands or data) therebetween via an inter-peripheral communication scheme (e.g., a bus, general purpose input and output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)).

According to an embodiment, commands or data may be transmitted or received between the electronic device 101 and the external electronic device 104 via the server 108 coupled with the second network 199. Each of the electronic devices 102 or 104 may be a device of a same type as, or a different type, from the electronic device 101. According to an embodiment, all or some of operations to be executed at the electronic device 101 may be executed at one or more of the external electronic devices 102, 104, or 108. For example, if the electronic device 101 should perform a function or a service automatically, or in response to a request from a user or another device, the electronic device 101, instead of, or in addition to, executing the function or the service, may request the one or more external electronic devices to perform at least part of the function or the service. The one or more external electronic devices receiving the request may perform the at least part of the function or the service requested, or an additional function or an additional service related to the request, and transfer an outcome of the performing to the electronic device 101. The electronic device 101 may provide the outcome, with or without further processing of the outcome, as at least part of a reply to the request. To that end, a cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technology may be used, for example.

In another embodiment, the external electronic device 104 may include an internet-of-things (IoT) device. The server 108 may be an intelligent server using machine learning and/or a neural network. According to an embodiment, the external electronic device 104 or the server 108 may be included in the second network 199. The electronic device 101 may be applied to intelligent services (e.g., smart home, smart city, smart car, or healthcare) based on 5G communication technology or IoT-related technology.

FIG. 2A to FIG. 2C illustrate an electronic device according to an embodiment. The electronic device 101 illustrated in FIG. 2A to FIG. 2C is an example provided merely for illustration, and the external appearance of the electronic device 101 is not limited to the external appearance of an electronic device described herein. For example, the electronic device 101 applied to this document includes a first touch screen display and a second touch screen display that are physically separated from each other, but a structure in which the first touch screen display and the second touch screen display are disposed to be in contact with each other without a joint or to be spaced at a certain interval (e.g., a gap of 1 mm or less) in an unfolded state (e.g., open state) may be applied.

Referring to FIG. 2A to FIG. 2C, according an embodiment, the electronic device 101 (e.g., the electronic device 101 of FIG. 1 ) may include a first housing 210, a second housing 215, a first touch screen display 220, and a second touch screen display 225. The first housing 210 and the second housing 215 may be connected to form the external appearance of the electronic device 101 and may provide a space in which components of the electronic device 101 are accommodated.

The first touch screen display 220 may be disposed in the first housing 210, and the second touch screen display 225 may be disposed in the second housing 215.

According to an embodiment, the first housing 210 and the second housing 215 may be connected to rotate or fold with respect to each other in at least one direction about one side (e.g., a-a′). For example, the first housing 210 and the second housing 215 may be foldably connected to each other through a hinge device 230 with respect to one side (e.g., a-a′) on which the first housing 210 and the second housing 215 are connected to each other. The electronic device 101 may be in various states (e.g., a closed state or an open state) according to a state (e.g., a folded state or an unfolded state) of the first housing 210 and the second housing 215. FIG. 2A shows that the first housing 210 and the second housing 215 are in an open state, FIG. 2B shows that the first housing 210 and the second housing 215 are in an intermediate state of being at a certain angle to one side (a-a′), and FIG. 2C shows that the first housing 210 and the second housing 215 are in a closed state.

When a front surface of the electronic device 101 is viewed with the first housing 210 and the second housing 215 open, the first touch screen display 220 may be exposed through a front surface of the first housing 210, and the second touch screen display 225 may be exposed through a front surface of the second housing 215.

When the second housing 210 and the second housing 215 are closed, the front surface of the first housing 210 and the front surface of the second housing 215 may be folded to face each other, and the first touch screen display 220 disposed on the front surface of the first housing 210 and the second touch screen display 225 disposed on the front surface of the second housing 215 may be folded to face each other.

The first touch screen display 220 and the second touch screen display 225 may be disposed adjacent to each other on the side (e.g., a-a′) on which the first housing 210 and the second housing 215 are connected to each other through the hinge device 230. For example, the first touch screen display 220 and the second touch screen display 225 may be in contact with each other without a joint on the side (e.g., a-a′) on which the first housing 210 and the second housing 215 are connected to each other, or may be separated by a certain interval (e.g., a gap of 1 mm or less).

The first touch screen display 220 may include a first glass 240 for protecting the display. The second touch screen display 225 may include a second glass 245 for protecting the display.

According to an embodiment, the first touch screen display 220 and the first glass 240, and the second touch screen display 225 and the second glass 245 may be configured to have a certain angle (e.g., 90 degrees) or a round shape on the side (e.g., a-a′). When the first touch screen display 220 and the first glass 240, and the second touch screen display 225 and the second glass 245 have the certain angle (e.g., 90 degrees) or the round shape, the first housing 210 and the second housing 215 may be changed to the open state, the intermediate state, or the closed state with a gap minimized.

For example, in the structure of the first touch screen display 220 and the first glass 240, and the second touch screen display 225 and the second glass 245, the displays are physically separate from each other rather than being a film type, thus not causing a distortion in a folding area, and an essential area (e.g., a decorative area) required for the film type is not required, thus making it possible to display a screen with a greater size than the film type.

According to an embodiment, a first digitizer panel capable of detecting a pen may be further disposed between the first touch screen display 220 and the first glass 240, and a second digitizer panel may be further disposed between the second touch screen display 225 and the second glass 245.

The electronic device 101 may independently operate the first touch screen display 220 and the second touch screen display 225, or may operate the two touch screen displays 220 and 225 as one display.

The electronic device 101 may output one integrated screen (or window) through the first touch screen display 220 and the second touch screen display 225, or may output a first screen on the first touch screen display 220 and a second screen on the second touch screen display 225. Alternatively, the electronic device 101 may split one integrated screen and may separately output split screens on the first touch screen display 220 and the second touch screen display 215 respectively.

FIG. 3 is a block diagram of an electronic device according to an embodiment.

For example, the first touch panel 322 and the second touch panel 332 may detect the touch or approach of the touch object through a pressure method, a resistance method, an infrared method, a sonic method, an optical method, or an electromagnetic induction method.

The first touch panel 322 and the second touch panel 332 may measure a physical quantity (e.g., a variance in capacitance) changed by the touch or approach of the touch object and may transmit the measured physical quantity to the touch control circuit. The touch control circuit may analyze the received physical quantity and may determine whether a touch input has occurred. Further, the touch control circuit may analyze the received physical quantity and may obtain touch information, such as the position or area of the touch input.

The touch control circuit may transmit the obtained touch information to the processor 310. In an embodiment, the touch control circuit may transmit the received physical quantity to the processor 310 as it is or in the form of partially processed raw data. In this case, the processor 310 may analyze the received data and may obtain the touch information, such as the position or area of the touch input.

According to an embodiment, the processor 310 may include one or more of a central processing unit (CPU), an application processor (AP), or a communication processor (CP), or may further include a graphic processing unit (GPU) and/or an image signal processor.

The processor 310 may determine whether a touch input has occurred using signal values input through the first touch panel 322 and the second touch panel 332. The processor 310 may determine touch information about a touch input, for example, a number of touch inputs, a position of a touch input, a time when a touch input has occurred, and a duration of a touch input.

The processor 310 may determine the type of a touch gesture input by the user, based on the touch information about the touch input.

The processor 310 may determine to output the content that changes to at least one of the first touch screen display 320 and the second touch screen display 330.

For example, the processor 310 may output an execution screen of a first application in a single window of a first size through the first touch screen display 320 and the second touch screen display 330.

In another example, the processor 310 may split or divide a single window, may switch to output the execution screen of the first application in a first split window of a second size corresponding to the first touch screen display 320, and may output another execution screen related to the first application or an execution screen of a second application in a second split window of the second size corresponding to the second touch screen display 330.

In another embodiment, the processor 310 may switch or expand an image output on the first touch screen display 320 to be displayed on the second touch screen display 330, or may switch or expand an image output on the second touch screen display 330 to the first touch screen display 320.

According to various embodiments, when the first touch input and the second touch input move in a third direction opposite to the first direction within the first boundary area and the second boundary area, the at least one processor 310 may be further configured to display a third execution screen different from the first execution screen in the first split window and display a fourth execution screen different from the first execution screen in the second split window, and wherein the third execution screen and the fourth execution screen may include execution screens of applications being executed in a background.

According to various embodiments, when the first execution screen is an execution screen of a first application and there is a designated function related to screen split corresponding to the first application, the at least one processor 310 may be further configured to display an execution screen related to the designated function as the second execution screen.

According to various embodiments, when the first execution screen is an execution screen of a first application and the screen split gesture is recognized in a state in which one of objects displayed on the execution screen of the first application is selected by a user input, the at least one processor 310 may be further configured to retrieve information related to the selected object and display a screen of the retrieved information as the second execution screen.

Further, the memory 340 may store at least one application. The memory 340 may include an internal memory or an external memory.

The sensor module 350 may measure a physical quantity that changes according to the open/closed state of the first touch screen display 320 and the second touch screen display 330, and may transmit the measured physical quantity to the processor 310.

According to an embodiment, the sensor module 350 may include a Hall sensor. The Hall sensor may detect a magnetic field generated by a magnetic body using a property of a voltage changing according to the strength of a magnetic field. According to an embodiment, the first touch screen display 320 and the second touch screen display 330 may be disposed respectively in the first housing and the second housing forming the external appearance of the electronic device 101, and the first housing and the second housing may rotate about one side to be open and closed. In addition, the Hall sensor may be disposed inside an edge area of the first housing, and the magnetic body may be disposed inside an edge area of the second housing.

For example, since the edge area of the first housing in which the Hall sensor is disposed and the edge area of the second housing in which the magnetic body is disposed approach to each other in a direction to face each other when the first housing and the second housing are closed, the Hall sensor may detect the magnetic field generated by the magnetic body. That is, when the strength of the magnetic field detected by the Hall sensor increases, the first housing and the second housing may be considered in a state of becoming closed, and when the strength of the magnetic field detected by the Hall sensor decreases, the first housing and the second housing may be considered in a state of becoming open.

FIG. 4 illustrates a display area of a first touch screen display and a second touch screen display according to an embodiment.

Referring to FIG. 4 , the electronic device 101 (e.g., the electronic device 101 of FIG. 1 ) according to various embodiments may include a first touch screen display 420 (e.g., the first touch screen display 220 of FIG. 2A or the first touch screen display 320 of FIG. 3 ) and a second touch screen display 430 (e.g., the second touch screen display 225 of FIG. 2A or the second touch screen display 330 of FIG. 3 ) which are physically separated from each other.

In the first touch screen display 420 and the second touch screen display 430, a boundary area (e.g., a first boundary area 421 and a second boundary area 431) for a screen split gesture recognition mode and a regular area (e.g., a first regular area 422 and a second regular area 432) for a general gesture recognition mode may be designated. Here, the boundary area and the regular area may refer to virtual areas divided by software rather than a physical division.

For example, the first touch screen display 420 and the second touch screen display 430 may be disposed adjacent to each other on one side (e.g., a-a′) on which a first housing 410 and a second housing 415 are connected to each other through a hinge device. In the first touch screen display 420, the first boundary area 421 may be designated adjacent to in a direction in which the second touch screen display 430 is disposed. In the second touch screen display 430, the second boundary area 431 may be disposed adjacent in a direction in which the first touch screen display 420 is disposed.

According to an embodiment, the electronic device 101 may recognize a general touch gesture, based on at least one a first touch input or a second touch input received from the first touch screen display 420 or the second touch screen display 430, and may perform functions (or actions) corresponding to the general touch gesture. Here, the general touch gesture may refer to a standard or universally designated touch gesture to operate or run the electronic device 101. For example, a touch for selecting an object may refer to a general touch gesture (e.g., a tap gesture) for executing an object, and a drag touch may refer to a general touch gesture for moving a screen.

According to an embodiment, the electronic device 101 may enter the screen split gesture recognition mode in response to the first touch input and the second touch input received in the first boundary area 421 and the second boundary area 431 satisfying one or more predetermined or configured conditions (e.g., time and/or moving direction), and may perform functions (or actions) related to a split screen (or separate display operation) by the first touch input and the second touch input.

For example, when a first touch is received in the first boundary area 421, a second touch is received in the second boundary area 431 substantially at the same time, and the first touch and the second touch are moved within the first boundary area 421 and the second boundary area 431 (or without departing from the first boundary area and the second boundary area) in a state of displaying a first execution screen in a single window of a first size through the first touch screen display 420 and the second touch screen display 430, the electronic device 101 may enter the screen split gesture recognition mode. Alternatively, the electronic device 101 may determine that a screen split gesture is recognized, based on movement of the first touch and the second touch within the first boundary area and the second boundary area.

For example, when a condition that the first touch is received in the first boundary area 421 and the second touch moves by a configured distance in one direction from the boundary areas in the second boundary area 431 is satisfied, the electronic device 101 may determine that a screen split gesture is recognized.

Upon recognizing the screen split gesture, the electronic device 101 switch the first execution screen displayed in the single window to be displayed (e.g., displayed in a downsized manner) in a first split window of a size corresponding to the first touch screen display 420 and may display a second execution screen in a second split window corresponding to the second touch screen display 430.

According to an embodiment, to enter the screen split gesture recognition mode, the electronic device 101 may further designate a first position 11 as a touch start point and a second position 12 as a touch end point within the first boundary area and the second boundary area. For example, when that the first touch and the second touch satisfy a condition of starting at the first position 11 which is a left point within the boundary areas and ending (e.g., being released) at the second position 12 which is a right point, it may be determined that the screen split gesture is recognized.

FIG. 5 illustrates a screen split method of an electronic device including a plurality of touch screen displays according to an embodiment.

Referring to FIG. 5 , according to an embodiment, in operation 510, a processor (e.g., the processor 120 of FIG. 1 or the processor 310 of FIG. 3 ) of the electronic device (e.g., the electronic device 101 of FIG. 1 ) may receive a first touch input from a first touch screen display and may receive a second touch input from a second touch screen display.

In operation 520, the processor 310 may determine whether the first touch input and the second touch input satisfy a screen split gesture condition.

According to an embodiment, the processor 310 may determine whether the first touch input is received in a first boundary area (e.g., the first boundary area 421 of FIG. 4 ) of the first touch screen display, the second touch input is received in a second boundary area (e.g., the second boundary area 431 of FIG. 4 ) of the second touch screen display substantially at the same time, and the first touch input and the second touch input satisfy a screen split gesture condition in a state of displaying a first execution screen in a single window of a first size through the first touch screen display 420 and the second touch screen display 430.

For example, the processor 310 may identify that the first touch is received in the first boundary area, the second touch is received in the second boundary area sequentially within a preset time (e.g., 1 sec) or substantially at the same time, and the touches are moving or have moved by a preset distance in a first direction from an initial first position to a second position. The first touch input may be a touch drag moving in the first direction within the first boundary area, and the second touch input may be a touch drag moving in the first direction within the second boundary area.

When identifying that the first touch input starting at a first position within the first boundary area has moved in the first direction and has been released at the second position and identifying that the second touch input starting at a first position within the second boundary area has moved in the first direction and has been released at a second position substantially at the same time, the processor 310 may determine that the first touch input and the second touch input satisfy the screen split gesture condition.

In operation 530, when it is determined that the first touch input and the second touch input satisfy the screen split gesture condition, the processor 310 may enter a screen split gesture recognition mode.

In operation 540, the processor 310 may execute functions (or actions) related to screen split according to movements of the first touch input and the second touch input when entering the screen split gesture recognition mode.

According to an embodiment, when the first touch input moves in the first direction within the first boundary area and the second touch input moves in the first direction within the second boundary area substantially at the same time in the state of displaying the first execution screen in the single window through the first touch screen display and the second touch screen display, the processor 310 may split the single window, may display the first execution screen through a first split window of a second size corresponding to the first touch screen display, and may display a second execution screen through a second split window corresponding to the second touch screen display. The size of the second split window corresponds to the size of the second touch screen display, and may be the second size the same as the first split window or may be a third size smaller than the second size.

The second execution screen may be a home screen or an execution screen related to an application being displayed on the first execution screen, but may provide various screens according to a configuration or design.

For example, when the first execution screen is an execution screen of a first application (hereinafter, “app”), the second execution screen may be at least one of a home screen, a different execution screen having a depth structure related to the first app, an execution screen of a second app related to the first app, or a function screen designated in response to a screen split condition in relation to the first app but is not limited thereto.

According to another embodiment, when the first touch input moves by a configured distance in the first direction within the first boundary area and the second touch input moves by a configured distance in the first direction within the second boundary area substantially at the same time in the state of displaying the first execution screen in the single window through the first touch screen display and the second touch screen display, after which the first touch input changes in a second direction perpendicularly crossing the first direction or the second touch input changes in the second direction perpendicularly crossing the first direction, the processor 310 may designate the position of a split window for displaying the first execution screen, may display the first execution screen in the split window at the designated position, and may display the second execution screen in a split window at a different position.

According to still another embodiment, when the first touch input moves in a third direction opposite to the first direction within the first boundary area and the second touch input moves in the third direction within the second boundary area substantially at the same time in the state of displaying the first execution screen in the single window through the first touch screen display and the second touch screen display, the processor 310 may display a third execution screen different from the first execution screen in a first split window corresponding to the first touch screen display and may display the first execution screen and a fourth execution screen in a second split window corresponding to the second touch screen display. The third execution screen and the fourth execution screen may be execution screens of tasks (or apps) being executed in the background while the first execution screen is displayed.

In operation 550, the processor 310 may maintain a general touch gesture mode when the first touch input and the second touch input detected in the state of displaying the first execution screen in the single window through the first touch screen display and the second touch screen display do not satisfy the screen split gesture condition.

For example, when the first touch input and the second touch input are not received substantially at the same time or the first touch input and the second touch input do not move in the boundary area (e.g., the first boundary area and the second boundary area), the processor 310 may maintain the general touch gesture mode. When the first touch input and the second touch are received at the same time but at least one of the start positions of the two touches, the release positions of the two touches, the moving distances of the two touches, and the times of the two touches does not satisfy the screen split gesture recognition conditions, the processor 310 may maintain the general touch gesture mode.

The processor 310 may identify a touch gesture mapped to at least one of the first touch input and the second touch input in the general touch gesture mode, and may execute a touch function corresponding to the touch gesture.

FIG. 6A and FIG. 6B illustrate a screen split method of an electronic device including a plurality of touch screen displays according to an embodiment.

Referring to FIG. 6A and FIG. 6B, according to an embodiment, in operation 610, a processor (e.g., the processor 120 of FIG. 1 or the processor 310 of FIG. 3 ) of the electronic device (e.g., the electronic device 101 of FIG. 1 ) may display a first execution screen in a single window through a first touch screen display (e.g., the first touch screen display 220 of FIG. 2A, the first touch screen display 320 of FIG. 3 , or the first touch screen display 420 of FIG. 4 ) and a second touch screen display (e.g., the second touch screen display 225 of FIG. 2A, the second touch screen display 330 of FIG. 3 , or the first touch screen display 430 of FIG. 4 ).

In operation 620, the processor 310 may determine whether a first touch input and a second touch input are received substantially at the same time in a first boundary area (e.g., the first boundary area 421 of FIG. 4 ) and a second boundary area (e.g., the second boundary area 431 of FIG. 4 ).

For example, when the first touch within the first boundary area of the first touch screen display and the second touch in the second boundary area of the second touch screen display are simultaneously received or when the first touch input and the second touch input are sequentially received within a configured time (e.g., 1 sec), the processor 310 may determine that the first touch input and the second touch input are received at the same time.

When the first touch input and the second touch input are not simultaneously received, the processor 310 may proceed to operation 630 and operation 635 to execute a touch function in a general gesture recognition mode.

In operation 640, the processor 310 may determine whether the first touch is within the first boundary area and whether the second touch is within the second boundary area.

When the first touch is not within the first boundary area and/or the second touch is not within the second boundary area, the processor 310 may proceed to operation 630 and operation 635 to maintain the general gesture recognition mode and to execute the touch function corresponding to a general touch gesture.

When the first touch is within the first boundary area and the second touch is within the second boundary area, the processor 310 may determine whether the first touch input and the second touch input satisfy a screen split gesture condition in operation 645.

When the times and moving distances of the first touch input and the second touch input do not satisfy a specified condition (e.g., the screen split gesture condition), the processor 310 may proceed to operation 630 and operation 635 to maintain the general gesture recognition mode and to execute the touch function corresponding to the general touch gesture.

When the first touch input and the second touch input satisfy the screen split gesture condition, the processor 310 may enter a screen split gesture recognition mode in operation 650.

When the first touch input and the second touch input satisfy the screen split gesture recognition condition, the processor 310 may provide graphic information introducing the screen split gesture recognition mode in operation 655. For example, the processor may display a screen split gesture recognition area (e.g., the boundary areas) to be visually distinguished from other regular area, or may display a screen split gesture recognition graphic user interface (GUI). In another example, the processor may display a touch gesture indicator, based on the first touch input and the second touch input received within the boundary areas.

According to an embodiment, operation 655 may be omitted.

In operation 660, the processor 310 may classify a screen split gesture by identifying movement conditions of the first touch input and the second touch input received within the first boundary area and the second boundary area.

In operation 670, the processor 310 may identify that the first touch input has started at a first position within the first boundary area and has moved by a certain distance in a first direction within the first boundary area and the second touch input has moved by a certain distance in the first direction within the second boundary area.

When the first touch input and the second touch input have moved by a configured distance in the first direction, the processor 310 may display a first execution screen in a first split window and may display a second execution screen in a second split window in operation 675.

In operation 680, the processor 310 may identify that the first touch input and the second touch input have moved by the configured distance in the first direction within the first boundary area and the second boundary area and then the first touch input and/or the second touch input has moved in a second direction perpendicularly crossing the first direction.

For example, the processor 310 may identify that the first touch input and the second touch input have moved by the configured distance in the first direction within the first boundary area and the second boundary area and then the first touch input has moved in the second direction perpendicularly crossing the first direction or the second touch input has moved in the second direction perpendicularly crossing the first direction.

When at least one of the first touch input and the second touch input has moved in the second direction, the processor 310 may assign a split window positioned in the second direction for the position of the first execution screen in operation 685.

In operation 687, the processor 310 may display the first execution screen in the split window at the assigned position and may display the second execution screen in a split window at a different position.

For example, when the first touch and the second touch have moved in the first direction within the first boundary area and then at least one of the first touch and the second touch has moved in an up direction (second direction) perpendicular to the first direction, the processor 310 may display the first execution screen in a split window positioned in the up direction (e.g., the first split window corresponding to the first touch screen display) and may display the second execution screen in a split window positioned in a down direction (e.g., the second split window corresponding to the second touch screen display).

In another example, when the first touch and the second touch have moved in the first direction within the first boundary area and then at least one of the first touch and the second have moved in the down direction (second direction) perpendicular to the first direction, the processor 310 may display the first execution screen in the split window positioned in the down direction (e.g., the second split window corresponding to the second touch screen display) and may display the second screen in the split window positioned in the up direction (e.g., the first split window corresponding to the first touch screen display).

In operation 690, the processor 310 may identify that the first touch input and the second touch input have moved within the first boundary area and the second boundary area but have moved in a third direction opposite to the first direction.

When the first touch input and the second touch input have moved in the third direction, the processor 310 may display a third execution screen different from the first execution screen in the first split window and may display a fourth execution screen in the second split window in operation 695. The third execution screen and the fourth execution screen may display tasks (or apps) being executed in the background according to an execution order (e.g., reverse chronological order).

FIGS. 7A and 7B illustrate screen split situations of an electronic device including a plurality of touch screen displays according to various embodiments.

Referring to FIGS. 7A and 7B, according to various embodiments, when a first touch input received in a first boundary area (e.g., the first boundary area 421 of FIG. 4 ) of a first touch screen display 710 and a second touch input received in a second boundary area (e.g., the second boundary area 431 of FIG. 4 ) of a second touch screen display 720 satisfy a screen split gesture recognition condition in a state of displaying a first execution screen of a first size in a single window through the first touch screen display 710 and the second touch screen display 720, the electronic device (e.g., the electronic device 101 of FIG. 1 ) may separately operate the displays to display a screen.

According to an embodiment, as shown in FIG. 7A, the electronic device 101 may display a home screen 7001 in the single window of the first size through the first touch screen display 710 and the second touch screen display 720. The home screen 7001 may be, for example, a screen displaying execution objects of an application installed in the electronic device 101.
